BACKGROUND ART

Recently, many people without distinction of age or sex enjoy swimming as part of exercises or leisure activities. Since such swimming is performed under or on the water, poor swimmers spend much time in learning how to flow on water before swimming and raising the level of swimming proficiency. Thus, people who are unskilled in swimming or have a low swimming proficiency have a limitation in enjoying swimming.

In an effort to solve this problem, an appliance or apparatus capable of assisting the swimming movement has been developed. as examples of such swimming assistance apparatus, there have been invented Korean Patent Registration No. 10-0699013 entitled “The Auxiliary Apparatus for Swimming”, Korean Patent Registration No. 10-0883892 entitled “The Auxiliary Apparatus for Swimming”, Korean Utility Model Registration No. 20-0232785 entitled “A Swimming Apparatus, Korean Utility Model Registration No. 20-0367463 entitled “Swimming Board, Korean Utility Model Registration No. 20-0429350 entitled “A Swimming Auxiliary Apparatus”, and Korean Utility Model Registration No. 20-0440240 entitled “Swimming Assistance Vest”.

To this end, the operating switch 44 is disposed at a distal end of a switch band 46 extending to the outside in such a manner as to be connected to the controller 40. Thus, the user can easily manipulate the operating switch 44 in a state of wearing the wearable swimming assistance apparatus 100.

In this case, the operating switch 44 may use an ON/OFF switch that performs only an ON/OFF operation, but may use a volume switch that can control the propulsive force of the water jet propeller 20 along with the control of the ON/OFF operation.

The buoyant member 50 is formed of Styrofoam having a buoyant force greater than a neutral buoyancy.

In the meantime, the wearable swimming assistance apparatus 100 according to an embodiment of the present invention includes a fixing band 60 formed on the body frame 10 so that the user's body can be fixed to the fixing band 60. The fixing band 60 includes a pair of shoulder fixing bands 61 that are fixed at the upper and lower ends thereof to the upper both sides of the body frame 10 so as to allow the user's shoulders to be retained in the shoulder fixing bands 61, a body fixing band 63 that is securely fixed at the left and right ends thereof to the body frame 10 so as to allow the user's body to be retained in the body fixing band 63, and a pair of leg fixing bands 62 that are fixed at the left and right ends thereof to the lower both sides of the body frame 10 so as to allow the user's legs to be retained in the leg fixing bands 62.
